摘要：

The synergistic effect of the MEHPA-DEHPA mixed system was examined for the extraction of Am(III) from nitric acid solution. Addition of DEHPA or 2-ethylhexanol in MEHPA results in a deleterious effect at MEHPA concentrations lower than 2·10-2M but an enhancing effect at higher concentrations. At DEHPA to MEHPA mole ratios of 2 to 4 in moles, the mixed solvent shows a Df for Am which is 1000 times higher than that of DEHPA. © 1979 Akadémiai Kiadó.
